"Alias" star Jennifer Garner didn't seem to the mind the recent rumors that her estranged husband Ben Affleck is already dating someone new.

According to the Daily Mail, the "13 Going on 30" star was spotted running errands with her three children Violet, Seraphina and Samuel. The publication also claimed that Garner smiled at photographers - something that she hasn't done in a long time since she and Affleck filed for divorce.

Meanwhile, Garner's recent sighting and body language coincided with The Hamilton Spectator's recent report. A source told the publication, "Jennifer was left heartbroken by her split from Ben but has told friends recently that she's ready to date again. She's moved on from Ben now and is ready to look ahead."

The source added that Garner and Affleck even went to therapy together, but not to help save their marriage.

"The therapy she and Ben had really helped Jennifer move on emotionally from Ben and heal her heartache. She no longer feels negative about marriage and has told pals she can imagine falling in love again and settling down. She'd happily have more children too," the source added.

In other news, Affleck and his rumored girlfriend Sienna Miller were reportedly recently spotted holding hands outdoors. Multiple sources claimed that the "Live by Night" co-stars have been acting sweet with each other on and off set.

"They're really flirty on set. Right now, Ben just wants to keep things casual so he can concentrate on his children. He's not looking for anything serious," an insider said.

Miller, meanwhile, recently split from her fiancé.

"Live by Night" is a movie that is also being directed by Affleck. It chronicles the life of a Prohibition-era bootlegger.

Ever since his divorce, Affleck has been spending time on the set of his upcoming movie.

"He is the first to arrive in the morning, sometimes as early as 5 a.m., and the last to leave at night," a source said.
